Axial piston variable pump A7VK Series 10 Metering pump for polyurethane components

▶ Sizes 12, 28, 55, 107 

▶ Nominal pressure 250 bar 

▶ Maximum pressure 315 bar 

▶ Open and closed design

Features 

▶ Compact design 

▶ Reduced dimensions and mass in comparison to A2VK 

▶ Mounting flange, drive shaft and functions identical to  A2VK, thus easy to replace 

▶ Increased corrosion protection through special surface  treatment 

▶ Manual adjustment with prescision display and clamp  unit to prevent accidental adjustment 

▶ Double shaft sealing made of special material and  flushing chamber to identify damage and protect environment 

▶ Improved volumetric efficiency through robust rotary  group using proven axial tapered piston technology 

▶ Optionally available with mounted high-pressure relief  valve 

▶ Low noise level

Closed design (A7VKG) 

▶ High permissible filling pressure for highly-viscous media or  hydraulic fluid by separating the filling channel and pump  housing 

▶ Case drain fluid must be discharged 

Open design (A7VKO)

▶ The housing is connected to the suction chamber. A case drain  line between the housing and reservoir is not requires
